IBM Akebono board device tree |
|
============================= |
|
|
|
The IBM Akebono board is a development board for the PPC476GTR SoC. |
|
|
|
0) The root node |
|
|
|
Required properties: |
|
|
|
- model : "ibm,akebono". |
|
- compatible : "ibm,akebono" , "ibm,476gtr". |
|
|
|
1.a) The Secure Digital Host Controller Interface (SDHCI) node |
|
|
|
Represent the Secure Digital Host Controller Interfaces. |
|
|
|
Required properties: |
|
|
|
- compatible : should be "ibm,476gtr-sdhci","generic-sdhci". |
|
- reg : should contain the SDHCI registers location and length. |
|
- interrupts : should contain the SDHCI interrupt. |
|
|
|
1.b) The Advanced Host Controller Interface (AHCI) SATA node |
|
|
|
Represents the advanced host controller SATA interface. |
|
|
|
Required properties: |
|
|
|
- compatible : should be "ibm,476gtr-ahci". |
|
- reg : should contain the AHCI registers location and length. |
|
- interrupts : should contain the AHCI interrupt. |
|
|
|
1.c) The FPGA node |
|
|
|
The Akebono board stores some board information such as the revision |
|
number in an FPGA which is represented by this node. |
|
|
|
Required properties: |
|
|
|
- compatible : should be "ibm,akebono-fpga". |
|
- reg : should contain the FPGA registers location and length. |
|
|
|
1.d) The AVR node |
|
|
|
The Akebono board has an Atmel AVR microprocessor attached to the I2C |
|
bus as a power controller for the board. |
|
|
|
Required properties: |
|
|
|
- compatible : should be "ibm,akebono-avr". |
|
- reg : should contain the I2C bus address for the AVR.
